Examples of BulkTransmitter

freenet.io.xfer.BulkTransmitter
Bulk data transfer (not block). Bulk transfer is designed for files which may be much bigger than a key block, and where we have the whole file at the outset. Do not persist across node restarts. Used by update over mandatory, sending a file to our peers attached to an N2NTM etc. @author toad
